This is not mine,I just searched found,and try a LOT of things. But this is the onlything that worked....
Step 1: DOWNLOAD
ADB Drivers - http://adbdriver.com/
ADB Shell (guide and download) - http://forum.xda-developers.com/showthread.php?p=48915118
kingo root - https://www.kingoapp.com/android-root/download.htm
Step 2: Command Prompt with ADB
run the CMD with admistrator privileges and use the following commands -
adb reboot disemmcwp
[Your device will now reboot with some extra write permissions]
install and run KINGO ROOT! (Yes, it's kingO root, not King) on your pc.
Now we need a custom recovery for it!
PS: o/! Dont try link2sd , because it #$&*#&(*@^*$ your apks, and you can't find it in the 2nd partition.
